Issues with latex math in markdown files, for display on Github Pages (using jekyll)
Our solution: use kramdown parser, with GFM option (Github flavored Markdown). In the .Rmd, use $$
for display math and $
for inline math. then have a script which turns the inline math demarkation in the .md file from $
into $$
when appropriate (avoiding data frame usage), before uploading the .md to Github. This way, RStudio preview looks the same as the Github Pages version.
- doesn't respect
$
or$$
(will parse characters within these, such as_
), but has workarounds: - has a useful option,
no_intra_emphasis
, so underscores between ascii characters are not converted to<em>
tags, so$x_1$
is fine - need to escape underscores after non-ascii characters, for example
$\mathbf{x}\_1$
- need to double escape curly bracket:
\\{
- need three backslash for new line
\\\
=
cannot be on its own line
- respects
$$
, will not interpret anything in between these. can be used for display or inline math doesn't respect$
for inline math, so then you need to escape all underscores (no such optionno_intra_emphasis
) and curly brackets here- need to double escape some characters within
$
, e.g.\\{
, which won't render in RStudio - you can however use
$$
for inline math:$$x_1$$
and even$$\mathbf{x}_1$$
work. Unfortunately$$
will become display math in the RStudio preview (although it will be fine with Github Pages)
hard-line wrapping is not allowed. So newline character will make new lines (whereas redcarpet and RStudio will make a paragraph from contiguous lines of text).turn off optionhard_wrap
- requires leading and trailing blank lines around
#
headers, while redcarpet will make a header even without a trailing blank line
- both can handle backtick-fenced code blocks, redcarpet by default and kramdown with
GFM
option (github flavored markdown)
good, tks ~~
